+ <p>A mechanism for limiting the amount of text that the

+ introduced. It is useful for limiting both the size of
+ log files and the CPU time used to produce them.</p>
+ <p>This mechanism is experimental in the sense that it
+ may be changed if it turns out that it does not solve the
+ problem it is supposed to solve. In that case, there may
+ be backward incompatible improvements to this
+ mechanism.</p>
+ <p>See the documentation for the config parameter
+ <c>error_logger_format_depth</c> in the Kernel
+ application for information about how to turn on this
+ feature.</p>
